Move unit_tests from chromium_gtests to chromium_gtests_for_devices_with_graphical_output.

chromium_gtests_for_devices_with_graphical_output means "not cast".
The cast build doesn't include anything at the //chrome level, and
unit_tests lives at the //chrome level.

Currently we have unit_tests in chromium_gtests which runs on all bots,
and then an exception to remove it again on the cast bots.

Instead, put it in chromium_gtests_for_devices_with_graphical_output so that
it only runs on non-cast bots in the first place.

(It also ends up removing unit_tests from linux-blink-heap-incremental-marking
and linux-blink-heap-verification on the fyi waterfall, since these bots run
chromium_gtests instead of chromium_linux_gtests -- that looks like a bot
config bug, but it's only FYI bots anyways.)

This removes the last "unclear why" comment from test_suite*.pyl!
